Description

Technical Field

[0001] This utility model relates to the technical field of modifier addition devices, specifically a modifier addition device for the production of heavy calcium carbonate. Background Technology

[0002] Heavy calcium carbonate (abbreviated as HCl, scientific name: heavy calcium carbonate powder) is a non-active inorganic filler prepared from natural minerals such as calcite, limestone, and marble through physical methods such as mechanical crushing and grinding. Because HCl is highly polar, while many substrates (such as plastics and rubber) are non-polar materials, the interfacial compatibility between the two is poor, easily leading to aggregation and uneven distribution during mixing. Modifiers alter the surface properties of HCl, reducing its surface energy and allowing it to better bond with the substrate.

[0003] For example, patent CN221492463U describes a device for adding modifiers to magnesium hydroxide slurry. The described solution is as follows: by setting up an adding mechanism, personnel can disassemble and install the entire mechanism, which facilitates subsequent cleaning of the filter box. The filter box can screen larger solid particles in the modifier, playing a filtering and screening role. At the same time, the rotation of the agitator blades will break up the solid particles in the modifier, which will facilitate full contact with the slurry inside the reaction tank, thereby improving the reaction rate between the modifier and the slurry.

[0004] When using the above technology, each time a modifier is added, the modifier needs to be added into the filter box, and then the modifier particles are screened to drop into the feed pipe. It is difficult to store different modifiers. At the same time, during the crushing process of the modifier, the filter box or crushing blade may cause the modifier dust to leak out.
